Justification entities:
These entities help you to support your models. Entities can be things, describers, amounts or relationships.
JUSTIFICATION
OBJECTS
Justification objects represent ideas or evidence. A justification object is
something you can use to help to support any ideas in your model.
Principle
A principle is a fundamental idea in science that many people agree on. Principles can be guiding ideas for scientists, such as the idea that claims have to be supported by evidence
Theory
A theory is a well supported idea in science that helps people to interpret what they see. The theory of gravity is a theory, as is the theory of evolution.
Hypothesis
A hypothesis is an educated guess about something. Usually, people make a hypothesis and then check to see if data supports it. For example, many scientists have a hypothesis that pollution is heating the atmosphere. They are checking to see if data supports it.Data
Data is information from the world that can be used to support a hypothesis or theory. Data could be experiment results or observations
JUSTIFICATION-RELATIONSHIPS
These relate evidence or other justification objects to your model. With these,
you can say if your model supports an idea or if an idea supports your model.
Might-Cause This is used to connect an observed change to a particular part of the model. Use it when uncertain about whether part of your model causes something. For example, Cars making CO2 might cause an increase in temperature.
Causes This is used to connect an observed change to a particular part of the model. Use it when fairly certain that one part of your model causes a change. For example, increase in melting ice caps causes sea level rise.
Supports Use this arrow to connect parts of the model to evidence or theories. You can use data to support some part of your model. Or you can use your model to support a hypothesis or theory.
Conflicts-With When part of your model conflicts with a theory or with data, use this arrow. For example, observations that things go up when dropped conflicts with the theory of gravity.
